A force failover can be performed on a Redundancy Cluster (RC) to swap an active server with its standby server. The servers this action can be performed on is determined by the RC's rcType:
  • Hot Hot: Force failovers can be performed on either the Active or Standby server and they simply swap roles.
  • Hot Cold: Force failovers can only be performed on an Active Server when the Standby server's current role is "Standby". The Standby server becomes "Active" taking the role of the Active Server on which the force failover was performed. The Active Server becomes Inactive.
  1. Click Elements > VUE in the navigation bar.
  2. Select a VUE system from the list which is a member of the RC to be failed over.
  3. Select the RC-Server tab.
    The RC table is displayed. There are two types which may be displayed:
    Hot-Hot
    1:1 VUE Redundancy Clusters always contain 1 Active Server and 1 Standby Server.
    Hot-Cold
    N:1 VUE Redundancy Clusters contain up to 10 Active Servers and 1 Standby Server.

  4. Select the RC row to be failed over.
  5. Click the (Menu) button.
    The menu options appear.
  6. Click Force Failover.
  7. Click Yes to confirm the suspension or Cancel to cancel the operation.
    NOTE:

    Forcing a failover to an unhealthy Active server may cause a subsequent automatic failover back to the Standby unless the Redundancy Cluster or Active Server is suspended from failing over automatically.

    To verify if the operation is complete, check the Current Role column in the RC-Server window.

Once the operation is complete, the VUE server forced to failover will go into Standby and the Standby server will replace the failed over VUE and become Active.
